Its a few days old, but here's Gizmodo's further take on the issue. I posted the blog they refer to earlier.

Sadly, I do not believe the 5S fits with the Apple ethos of making the best devices. Like Antennagate, owners will only become aware of the sensor issue if they find the phone is behaving strangely. Once outside the 14 day new replacement, they may have to be content with a refurb phone, that may have the same issue until it is fixed properly.

We can only speculate whether Jobs would have tolerated this apparent design flaw pre release of the phone to manufacture. I suspect the answer is that he wouldn't.

I suspect he would. You mentioned it yourself: antennagate.
 

Thanks! Mine seems right on so far. Think I got lucky.

Were you up all night?
 
Were you up all night?

I checked the inventory online last night after they closed, then slept in and made my way there and picked one up. A lot of people there buying them (5 other people while I was getting mine and quite a few waiting) of course they didn't have any gold at all. They told me they only received silver and grey.

Checked again, all sold out now.
 
Thanks! Mine seems right on so far. Think I got lucky.

Is this the first F2 factory made phone we have seen so far???
Think this is the first I see, if so there might be hope that phones made there are already calibrated correctly?
 
Clinometer App is Free today

Hi All,

People have been using Clinometer to test their iPhones.

Clinometer is free today (save 99 cents), so worth downloading to test your iPhone.

So I tested it against my ipod using ihandy level and it was within ~1 degree. Reset calibration settings on both and got similar results. Compared to reading on the compass app, the 5s shows about 1 degree difference between ihandy level and the built in app.

Edit: Tested clinometer also, when zeroed and then flipped 180 the readings were 0, 180 and 0,179. Seems to work correctly.

My 5s is coming on Monday from that factory, shipped on 17 of October. I'll keep you posted.

Edit: will be a week 42

hey patrek,
where did you buy it ?
I mean which country ?

Because I get the 2nd one from from C3 factory.
And I was wondering if different factories have different calibration standards.
 
I ordered it from France, i'll post here as soon as it is delivered. I really hope it is ok because there's no apple store near where i live...
 
I've cancelled my order until there is an official fix, OR until we can confirm without a doubt that new shipments do not have this issue.
 
Hi everyone.
I want to make a small contribution to this very interesting thread.
The biggest question of every buyer/future buyer is about this problem being a hardware or software one.

Well I have good news and no so good news.
Eagle Jones from RealityCap had done a great job measuring the accelerometer output, and he found that those values had some "offset". This is an small amount of variation over the real value, and can be positive or negative and also would be different for each axis (x, y and z). So, if in a giving position, your iPhone 5S accelerometer should "read" 1g over one axis, it could actually read 1.05g or 0.95g. This variations are different from sensor to sensor and they depends of several manufacturing process.

The good news are that the sensor used (that is indeed a Bosch part, but we don't know which one: http://www.chipworks.com/components/com_wordpress/wp/wp-content/uploads/2013/09/bosch.jpg), had a non-volatile memory were the offset compensation values could be stored.
Why this part wasn't calibrated at the iPhone assembly line we will never know.

The no so good news: some Apple staff had been recommending the DnD and charge procedure, but let me be clear on this: THAT WOULD NEVER WORK.
Your iPhone had an internal 3 AXIS accelerometer. If you left your iPhone lying flat and supposedly "trigger" the calibration by DnD and charge, you are, in the best of cases, calibrating A SINGLE AXIS. A flat up iPhone would only been using the z axis. Remember that each axis have their own offset (negative or positive). In order to fully calibrate the iPhone you need to measure the difference between gravity and the accelerometer output in vertical, landscape and flat positions AND those should be as close as perfect as they could be, otherwise you would end with wrong compensation values.

You may asking why the above isn't a good news, since the sensor could be calibrated. Well, call me skeptic, but I hardly believe that Apple would admit any wrongdoing or that it would recommend hold the iPhone in 3 different positions while the sensor is calibrated. Neither we would see a recall.

Could this be fixed by a software update? This is a tricky question. If Apple "captures" devices assembled in every possible week or day they could, theoretically, measure the offset present in every accelerometer. iPhone's assembled near a single date should use accelerometer's manufactured in a small range of time, and, again theoretically, parts manufactured in a single batch should have similar characteristics. Based in those assumptions, is relatively easy to release a HARD CODED offset compensation, that would be applied in function of the building date of the iPhone. Of course this would be a single iOS 7 release, but internally they can customize what it does (in the same way that they apply the yellow wallpaper to the yellow iPhone 5C and no to another).

Problem with the HARD CODED offset compensation? It would be far from perfect, but supposedly better than the current deviation. At least it doesn't requires that the user put the iPhone in different orientations.

The second alternative to Apple, is do nothing and let the developers to build calibration routines inside their apps.

I want to suppose that the iPhone's being assembled now are properly calibrated.
Is important to keep this thread alive, and even more important, that the new owners publish their building date to confirm the above.

Disclaimer: all the stated above is my best guess on the issue. As I don't work for Apple, neither I had access to their software or hardware, I cannot assure or guarantee that my conclusions are valid.

I will follow up with a more detailed post when I have completed "restoring" my white box replacement I got today from Apple.

I just wanted to say that it is odd that the above posted used the word "capture" when talking about Apple. I noticed the "genius" who was assisting me said to another person working there, "Hey (name), are we will CAPTURING 5S's?" The person said yes.

I sat and thought for about one minute. I then asked him to clarify what that meant. He said it is a term used within their store meaning they are retaining certain phones to send to engineering to have problems and issues studied, and yours is a prefect candidate."

Ill post back later. This is my first post on this board, but I have been following it for about 2 weeks.

John
 
The ones they should be "capturing" are the rare few that are calibrated correctly. Send those back and figure out what went right.
 
Ok, well.

My production week on the original phone was 37, this one is 39. I dont have the details in front of me, but when I reviewed them at the app store, they were from different factories, but they were both from factories within China.

The replacement Iphone: It's off -1. Sometimes 0. But so far, -1.

The original iphone, which I had ordered online when they first came out was -3 to -4.

I bought apple care while I was there. For some reason, I got the vibe that they werent happy about adding applecare to a phone issued by the store as a replacement, so an "administrative genius" had to come out to the floor to do the transaction.

Everything else seems to work as normal. I'm not happy still. But I'm not going to take the time to go back to that hell hole of un-educated people and sweat it out waiting for my appointment.

Some dude came in asking for the "lenses," an employee was like, uh, huh? I said, are you looking for google glass? The man spoke spanish. He said yes. The employee said you cant buy those here. I told him, you cant buy them anywhere.

Also, I had to show the employee had to get to the compass app, then he honestly acted like he had never calibrated, or been to the compass app on the phone. He was clueless. He however agreed my phone was bonk.

I checked out two other phones on the floor. One was off -3, the other -2.

Oh, by the way, my phone came with 7.0.0 installed.

It's the same, calibration wise, with 7.0.0 and 7.0.2.

dissapointed, but will keep checking the thread,

John, in Oklahoma City.

ps. too lazy right now to spell check. or even use caps.

No. My employee has an F2 phone and it's a whopping 6 degrees off.

They sent mine off to engineering too, my fellow Oklahoman.

Lol this app crashes 100% of the time, very bad. Or is it just me who's experiencing this?

not crashing on my 5s as well.


ps whats the use of this app? after calibration my leveler still shows the same values :/

So does that mean that they are still looking at the calibration problems and haven't applied a fix yet
 
iPad 5 & iPad Mini 2, gyro problems?

New iPads out on Tuesday with rumors of M7 chip, I wonder if we'll see the same issues with the gyro sensors?? I'm going to be holding off and playing the waiting game.
 
What's the % of iPhones having the gyroscope issues? I was planning on ordering one this week, but now I have major concerns whether to do it or not.

I don't like to gamble.
